Fire Suppression system......discharge rate for a certain bottle pressure? Need Help! 1

[ChasGen61]

System has multiple lines connected. I don't know how to calculate what bottle pressure I will need for various lines coming off the bottle with a particular nozzle. Is there any software in the public domain that can calculate what bottle pressure I will need?

Chas, I'm guessing this is a CO2 system? Regardless of your location and what relevant standards apply, NFPA 12 is a good place to start (it's referenced by a lot of other standards). I'm unaware of any free software. From my experience, fire protection tends to be a pretty niche area (which is not my niche, by the way) where knowledge is kept within house, so I'd be doubtful if you could find any free software. There's plenty of non-free fire protection software packages out there (ex. Janus).

Here are some examples of good technical references:
one
two

There is also a NFPA sub-forum which might be able to help as well.
